Hardware for Linux gaming PC

The draft is pretty good. Only a few points to consider changing:

  • That is an entry level Motherboard which may limit your upgrades in the future. It overheats with a 16 core ryzen 9.
  • The ram size is good, but the speed and latencies are just as important nowadays. A 6000 MT/s CL30 Expo ram could improve CPU performance, but it's a kind of OC so not every combination is fully stable at the highest speeds.
  • Especially with competitive and indie games it's easy to run them at high FPS. I would consider getting a 1440p high refresh rate (144+ Hz) monitor if you don't have one already. It's a huge upgrade coming from 1080p60Hz.

Steam Next Fest is currently ongoing - which demos did you like/dislike?

Stormgate

It's like 90% StarCraft 2 and 10% Warcraft 3. The competitive RTS part is promising but it didn't show me anything new. Depending on the lore and campaign it may get more interesting, so far it's neutral.

Millennia

It starts very similarly to Civ 6 with even more kinds of resources. The current version of the UI seemed confusing and the poor performance (on linux) stopped me from finishing the demo.

in your opinion, what is the biggest downside of Flatpaks?

Filesystem permissions

For many apps it is not an issue and provides additional security but in other cases it's very annoying and not trivial to fix.

Example1: opening a .docx from Thunderbird flatpak with OnlyOffice flatpak does not work out of the box.

Example2: mpv and VLC flatpaks work well for local files, but fail to open network shares from Dolphin.

I think a possible solution would be runtime permission dialogs when denied access.

What is your experience with btrfs snapshots?

The FS feature is great, it's just cumbersome to use without a tool.

Snapper works well for a local backup like history both against botched updates and accidental deletion, but eats up the free space with the default settings.

Timeshift is an easy to use GUI but doesn't support non-default partitions.

Also the quota support had a nasty side effect: freezing the whole system on snapshot deletion.

As an Android flavour it should be safe after uninstalling all apps associated with the university. Did any of them need a "device owner" permission? That's the only way to be more persistent on Android without root access.

Unexplained reboots and kernel panic

What troubleshooting steps did you take so far? I would try these:

  • different OS, maybe a live usb running fedora or ubuntu if it is possible to emulate the workload where this appears
  • bios reset to defaults, no OC not even XMP
  • memtest, either the memtest86+ boot iso or the runtime memtester can detect obvious errors
  • long smart self test on OS drive and an fsck or scrub based on FS

Also the logs show a very old nvidia gpu which is not supported by the new driver. I don't know if this can cause crashes, haven't used one in ages, maybe someone else has more insight.

Help on BTRFS setup

Do I need to disable compression on my swap subvolume?

Short: No

Long: it doesn't matter when mounting multiple subvolumes of the same btrfs partition the options from the first one (usually /) will apply to all. So even if you disable it, that will be ignored.

The old way of creating swap shows the chattr +C line which disables CoW. The same method should work for your Downloads folder since CoW is needed for snapshotting.

How to screen a 20TB library for corrupted files?

Reply in thread

Navigate to a problematic movie or episode -> 3 dots -> Get info -> right column -> Color space

Usually SDR is bt709 and HDR is bt2020. In older codecs (h264) 10 or 12 bit color depth can also cause issues.

I'm not sure how tone mapping works on plex since I don't have a pass but with Jellyfin you need to setup OpenCL which is run on the GPU so your guess that a hardware change can break it is plausible.

Out of touch old timer planning a new build

Looks pretty good for your needs.

  • Depending on local pricing the non-x R5 7600 could save a bit for just a minor clock speed reduction.
  • You did not list the latency of your RAM. Going down to CL30 could increase CPU performance.
  • The 3060 is good for AI on the budget. For gaming a 6700XT would be better if your software tools are well supported on AMD.
